ABSTRACT The present invention relates to a unique chemical formu- lation used in the manufacture of substantially wind- resistant, water-repellent fabrics. The formulation com- prises a silicone polymer catalyzed with a tin compound and optionally includes acetic acid and an aromatic sol- vent. A method for treating fabrics includes depositing the unique formulation on a taut fabric, uniformly distribut- ing it across the width of the fabric and curing that product. Either before or after that treatment, the fabric is padded with or dipped in a bath of silicone or hydro- fluorocarbon. Excess solution is removed. Last, the multicoated fibers of the fabric are compressively shrunk. A substantially wind and water-resistant fabric is pro- duced that is not only porous and soft but also durable.
